DESCRIPTION
The low voltage X4C105 combines several functions
into one device. The first is a 2-wire, 4Kbit serial
EEPROM memory with write protection. A Write Pro-
tect (WP) pin provides hardware protection for the
upper half of this memory against inadvertent writes.
A one nibble NOVRAM is provided and occupies a sin-
gle location. This allows access of 4-bits in a single
150ns cycle. This is useful for tracking system opera-
tion or process status. The NOVRAM memory is com-
pletely isolated from the serial memory section.
A low voltage detect circuit activates a RESET pin
when V
CC
drops below 3V. This signal also blocks new
read or write operations and initiates a NOVRAM
AUTOSTORE. The AUTOSTORE operation is pow-
ered by an external capacitor to ensure that the value
in the NOVRAM is always maintained in the event of a
power failure.
The four NOVRAM bits also appear on four separate
output pins to allow continuous control of external cir-
cuitry, such as ASICs.
Xicor EEPROMs are designed and tested for applica-
tions requiring extended endurance. Inherent data
retention is greater than 100 years.
